Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The design and manufacturing of special-shaped display panels for mobile devices face challenges due to the increased complexity in wiring around holes, leading to a larger ineffective light emitting area and compromised aesthetics.
Innovation Solution
A display panel design featuring a DEMUX circuit and data line layout where first data lines extend along the side edge of the hole area, while second data lines do not occupy the light emitting area, with the DEMUX circuit and driving IC used for gating, reducing the wiring width and ineffective light emitting area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If data lines are routed around the hole area in traditional layouts, then connectivity is maintained, but the wiring area increases and aesthetics deteriorate
Solution Approach 1:
The data lines are segmented into first segment lines and second segment lines, with the first segment lines extending along the side edge of the hole area and the second segment lines connected through connection lines. This segmentation allows the wiring to follow the contour of the hole area more efficiently, reducing the overall wiring area while maintaining connectivity.
Solution Approach 2:
The data lines are arranged in a multi-dimensional layout where every adjacent n+1 data lines form a data line group with specific spatial relationships. The connection lines extend along the side edge of the hole area in a direction that optimizes space utilization, transitioning from traditional planar routing to a more sophisticated spatial arrangement that reduces wiring area.
2Quantity of substance
If more data lines are routed around the hole area, then pixel coverage is improved, but device complexity increases
Solution Approach 1:
The DEMUX circuit is introduced to provide universal control for multiple data lines. The circuit includes n gating control lines that can individually gate each of the first data lines and gate each of the second data lines through the first data line in each data line group and the DEMUX circuit. This multi-functional control mechanism simplifies the overall system complexity while managing a large number of data lines.
Solution Approach 2:
The DEMUX circuit acts as an intermediary between the driving IC and the multiple data lines. Instead of directly controlling each data line from the driving IC, the DEMUX circuit mediates the control signals, gating the second data lines through the first data lines. This intermediary structure reduces the complexity of direct multi-line control while maintaining individual line control capability.
3Area of stationary object
If connection lines extend along the side edge of the hole area, then wiring area is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The connection lines are specifically designed to extend along the side edge of the hole area, creating a localized wiring pattern that optimizes space utilization in this specific region. This local quality approach allows the wiring to adapt to the hole area's geometry, reducing the overall wiring area while concentrating precision requirements to specific critical connection points rather than the entire wiring structure.
